The Dev Server is currently only used for previewing major updates, and I think this should change. Instead of only using it about 5 times a year (along the same schedule as the updates for 2-4 weeks), I think the dev server should be used to test new game mechanics and BR changes as well. For example, imagine the ARH playtest during the Dev Server for Alpha Strike, but on a more regular basis for testing things like electronic warfare, stealth, IIR seekers, BR changes etc. Then, players would be surveyed on if they think the changes should be implemented or changed. Players would be more heard, and Gaijin can safely test game changed outside of just updates or April Fools events.
